Oncologic results and quality of life in patients with squamous cell carcinoma of hypopharynx after transoral laser microsurgery

Objective: Transoral laser microsurgery (TLM) is an alternative method for organ preservation in squamous cell carcinoma of hypopharynx (HPSCC). The purpose of this study was to analyze the oncologic results and quality of life (QOL) in HPSCC patients after TLM. Methods: Forty-six patients who underwent TLM were included, 34 of them had QOL evaluations. The QOL analyses were measured with EORTC QLQ-C-30, QLQ-H&N35, VHI-30, and MDADI at least 6 months postoperatively. Results: Most patients were male (96%) with a median age of 60 years. Four patients (9%) were at the T1 category, 24 (52%) at T2, 15 (33%) at T3, and 3 (7%) at T4. Twenty-nine patients (63%) had cervical lymph node metastases and 26 (57%) received postoperative radiotherapy. With a median follow-up of 61 months for all patients, 18 (39%) had tumor recurrence, including 4 local, 7 regional, and 7 distant. The 5-year overall and disease-specific survival (DSS) rates were 59% and 77%, respectively. The 5-year laryngeal preservation rate was 89%. Most patients had satisfactory QOLs. Conclusion: In early and selective moderately advanced HPSCC, TLM can achieve optimal oncologic results and satisfactory QOL. Lasers Surg. Med. 50:117–124, 2018.
